Cleansing efficacy of the electric toothbrush Oral-B iO™ compared to conventional oscillating-rotating technology: a randomized-controlled study.

Objectives: This study aimed to compare the cleansing efficacy of the Oral-B iO™ electric toothbrush incorporating oscillating-rotating technology with microvibrations - with a traditional oscillating-rotating toothbrush.

Materials And Methods: Thirty adult participants were randomly assigned to use the iO™ electric toothbrush with the brush head iO™ Ultimate Clean or the traditional oscillating-rotating toothbrush Oral-B Genius with the Cross-Action brush head. Oral hygiene indices (Rustogi Modified Navy Plaque Index and Gingival Bleeding Index) were assessed before and after 28 days of home use of the assigned product.

Using Video-Reflexive Methods to Develop a Provider Down Protocol for the New South Wales Biocontainment Center.

The New South Wales Biocontainment Centre is a statewide referral facility for patients with high-consequence infectious disease (HCID). The facility collaborates with researchers to adapt existing HCID procedures such as donning and doffing of personal protective equipment (PPE). However, information on how to respond safely to collapse of a healthcare provider in full PPE within a contaminated zone is scarce.

Broken Rotor Bar Detection Based on Steady-State Stray Flux Signals Using Triaxial Sensor with Random Positioning.

This paper investigates the detection of broken rotor bar in squirrel cage induction motors using a novel approach of randomly positioning a triaxial sensor over the motor surface. This study is conducted on two motors under laboratory conditions, where one motor is kept in a healthy state, and the other is subjected to a broken rotor bar (BRB) fault. The induced electromotive force of the triaxial coils, recorded over ten days with 100 measurements per day, is statistically analyzed.
